In the scorching summer, all kinds of fresh fruits are on the market in large quantities
For these delicious and juicy fruits
It has always been circulated among the people
"Peaches raise people, apricots hurt people, and bury dead people under plum trees".
So, what are the facts?
Let's find out today.
From May to October every year, plums are on the market, especially in July and August, which is the peak season for eating plums. As a common fruit, plums can be eaten raw, can also be made into preserved fruits, or canned food, brewing, etc. Not only is it delicious, but it's also highly nutritious.
Tian Jing, associate professor at the College of Food Science and Technology of Huazhong Agricultural University: "Plum is a relatively good fruit, and it has many benefits. The first of the two is that it is relatively low in calories, which is very suitable for weight loss, about 100 grams has 38 calories in it, which is equivalent to the calories of a small bowl of raw vegetables. Second, it has a relatively low sugar content and a low glycemic index, which is very beneficial to people who control blood sugar. Third, it's high in dietary fiber, which can provide you with a feeling of fullness and laxative. Fourth, it is rich in anthocyanins and has a good protective effect. ”
As for the folk saying, "peaches raise people, apricots hurt people, and bury dead people under plum trees", experts believe that it may be related to two aspects.
First, the tannin content is relatively high. If it is an unripe plum, the tannin content is higher, so it will taste bitter and astringent. It is easy to combine with protein, on the one hand, it can affect the digestion and absorption of protein, on the other hand, it can affect the activity of digestive enzymes, and eventually there will be symptoms of indigestion such as bloating and abdominal pain. Second, the kernel of the plum contains cyanogenic glycosides, which are not toxic by themselves, but after eating, they may hydrolyze to produce substances such as hydrocyanic acid, which may cause poisoning symptoms. Mild poisoning will have nausea and vomiting, abdominal pain and bloating, and more severe poisoning will cause symptoms such as suffocation and respiratory paralysis.
According to experts, the fruit acid in plums can indeed stimulate gastric acid secretion, but as long as it is not excessive, for healthy citizens, there is no need to worry about discomfort.
However, if you have excessive gastric acid secretion or gastric ulcers, it is recommended to choose plums that are sweet and less sour and eat them in small quantities to avoid aggravating the condition. So how to eat plums for health science?
Tian Jing, associate professor of the College of Food Science and Technology of Huazhong Agricultural University: "According to our understanding of plums, the first thing to eat plums is to choose ripe, and when you buy it, you should press it. The second point is to eat with the skin, the content of anthocyanin polyphenols in the skin is higher, and the crude fiber is higher, which is conducive to relieving constipation. The third is to eat between meals, and the satiety coefficient of dried plums is higher than that of low-fat biscuits, which has a good effect on relieving hunger. Finally, no matter how good the plums are, we should eat them in moderation, not more than 350 grams. ”
According to the dietary guidelines for Chinese residents, it is recommended to eat 200 to 350g of fruits per day. However, considering that the flavor and nutrition of different fruits are different, it is recommended that plums can be eaten with other types of fruits, 5~7 pieces per day for small ones, and 2 or 3 pieces for large ones.
